Background: It is known that calcium channel blockers are associated with a risk of gingival
hyperplasia. These drugs are widely used in the management of gestational hypertensive disorders.
Case: A 27-year-old G1 woman presented with gingival hyperplasia at 27 weeks gestation during a
hospitalisation for preeclampsia. She had been on nifedipine for hypertension for the last 9 weeks.
Nifedipine was discontinued and replaced by methyldopa and already after 48 hours the gingival
hyperplasia improved. She delivered two weeks later and the gingival hyperplasia resolved completely
without surgical intervention. The Naranjo’s score was used to prove the nifedipine’s imputability.
Conclusion: This first case report of gingival hyperplasia induced by nifedipine in pregnancy could be
used as a reference for clinicians in the management of this adverse effect during the pregnancy.
